Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745378, here are decompositions:

11 + 8745367 = 8745378
67 + 8745311 = 8745378
71 + 8745307 = 8745378
79 + 8745299 = 8745378
137 + 8745241 = 8745378
139 + 8745239 = 8745378
151 + 8745227 = 8745378
179 + 8745199 = 8745378

Showing the first eight; more decompositions exist.
